Keep the electrons flowing and the tubes glowing.

The people who run the website EE Web have
interviewed me and written a very
nice article. Here is the link.

An Observation.
If I worked on radios the same way doctors worked on people when ever a capacitor, resistor, or tube, failed I would just take it out and throw it away. Yet the radio would be expected to work as well as when it was new. So far I am down my tonsils, adenoids, about one and a half feet of large intestine, and a gall bladder. My power output is down and my distortion percentage is up.
It's called Fun With Tran-sisters. If you would like to tinker with electronics But you would rather not poke around among High voltages, check it out. |

What do I need to have fun with tubes?

Everything you always wanted to know about |
I have a master's degree in electrical engineering from the University of Florida 1966. My early EE classes covered vacuum tubes so I know what I am talking about and doing. If you have any questions or suggestions feel free to email me.
On a number of occasions I have received emails from people seeming to be asking legitimate questions. When I attempt to answer them I get back one of those "Mail System Error" messages saying that there is no such address or my email address has been blocked by the sender. Some anti spamming programs are quite strict and maybe you forgot to enter my address as "allowed". Check your anti spam list to be sure my reply will be given to you instead of being bounced back to me.
On the other hand maybe this is someone's idea of juvenile fun. No doubt the people who have done this (you know who you are) think this is very funny. To me it's just a minor annoyance. Even though it's a small thing I could do without it. Just because you're not having fun don't spoil it for the rest of us.

Who and What.
This web site is owned and operated, as a hobby, by Max Robinson. As time goes by I will post tutorials on the fundamentals of electricity and electronics, interesting circuits you can build with vacuum tubes and op amps, and I will share some of my experiences restoring antique radios and early electric phonographs.
If I Don't Answer...
I scrupulously answer all emails sent to me. If you send me one and you don't hear from me in a reasonable amount of time maybe something went wrong.
